Ingredients

To make these delicious Cheesy Scalloped Potatoes, gather the following ingredients:

For the Base

4 russet potatoes, (peeled and sliced into ¼-inch slices (about 2 pounds))
1 yellow onion, (sliced into rings)

For the Cheese Sauce

3 tablespoons unsalted butter
3 tablespoons all-purpose flour
½ teaspoon kosher salt
2 cups whole milk, (room temperature)
1 ½ cups mild cheddar cheese, (shredded)
Salt and pepper to taste

How to Make Cheesy Scalloped Potatoes

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Lightly spray an 8×8-inch casserole dish with nonstick cooking spray to prevent sticking.

Step 2: Layer the Potatoes and Onions

Arrange the sliced potatoes and onions in the prepared baking dish. Stagger each layer by alternating between potato slices and onion rings for even flavor distribution.

Step 3: Prepare the Cheese Sauce

In a medium-size saucepan over medium heat:
1. Melt the butter until bubbly.
2. Mix in the flour and salt, stirring constantly with a whisk for one minute.
3. Gradually stir in the milk until well combined. Cook until thickened.

Step 4: Add Cheese

Once thickened, add all of the shredded cheese at once. Stir continuously until melted and smooth, which should take about 30–60 seconds.

Step 5: Combine Everything

Pour the cheese sauce evenly over the layered potatoes and onions. Cover the casserole dish tightly with aluminum foil.

Step 6: Bake

Place the covered casserole in the preheated oven and bake for 85–90 minutes or until the potatoes are tender when pierced with a fork.

Step 7: Broil for Crispiness

For a golden-brown topping, switch your oven setting to broil after baking. Broil until crispy on top—keep an eye on it!

Step 8: Season and Serve

Remove from oven, season with salt and pepper to taste, then serve hot as an outstanding side dish!

Common Mistakes to Avoid

When preparing Cheesy Scalloped Potatoes, it’s easy to make some common mistakes. Here’s how to avoid them for a perfect dish every time.

Bold Potato Slicing: Cutting the potatoes too thick can lead to uneven cooking. Make sure to slice them into ¼-inch rounds for consistent texture.
Bold Ignoring the Onions: Overlooking the addition of onions can result in a one-dimensional flavor. Slice them thinly and layer with the potatoes for a sweet, savory boost.
Bold Skipping the Cheese Sauce: Failing to create a proper cheese sauce can lead to dry potatoes. Take the time to melt the cheese into a smooth sauce for a creamy finish.
Bold Not Covering While Baking: Baking without covering can cause the potatoes to dry out. Use aluminum foil for the first part of baking to keep moisture in.
Bold Forgetting Seasoning: Neglecting to season your dish will lead to bland flavors. Always season with salt and pepper after baking for enhanced taste.
